BACKGROUND

Laparoscopic transvaginal natural orifice specimen extraction (NOSE) procedure, as one of sub-surgical procedure selections of NOSE, has been well discussed recently. Although most studies argued receiving better post-surgical outcomes than laparoscopic right hemi-colonic radical resection, disadvantages of laparoscopic transvaginal NOSE have seldom been reported. Herein, we reported a case with an overwhelming infection after laparoscopic transvaginal NOSE, even leading a sudden cardiac arrest, and also performed a review of the literature of NOSE, in hopes of expending experience with NOSE for every general surgeon.

CASE PRESENTATION

A 78-year-old female patient was diagnosis with ascending colon carcinoma (cT3N0M0). After pre-surgical preparation, a laparoscopic transvaginal NOSE was performed. At the 1^st day post-surgery, a septic shock was manifested, with an acute cardiac failure. An intensive care unit therapy was given immediately, including anti-inflammatory therapy, anti-shock therapy, cardiac functional supporting therapy. At the 2^nd day post-surgery, there was a sudden cardiac arrest. A cardiac emergency treatment was immediately given to her, following a comprehensive therapy. After a supporting treatment, this patient was discharged from our department at 12 days post-surgically, with a normal manifestation of blood pressure level, breath rate, heart rate, body temperature, white blood cell count, et al. However, a complaint of intermittent precordial pain still existed when discharging from our department. She was transferred to cardiovascular medicine department for a further treatment on cardiac function then. After another 18 days treatment, she left from hospital.

CONCLUSIONS

Considering many clinical trials on NOSE with positive clinical outcomes, NOSE was recommended to an optional surgical treatment for gastrointestinal carcinoma. However, this case report reminders general surgeons that post-surgical complications to NOSE, some are even fatal, still has possibility to come out. A thorough evaluation pre-operationally and an appropriate therapy post-operationally are crucial and inevitable.

case report

With an accumulation of clinical trials on laparoscopic colectomy for colonic carcinoma from many different single and/or multiple centers, the advantages of such procedure have been discussed and confirmed by surgeons.[1 2] However, an around 5cm incision would be left on abdominal wall for specimen extraction postoperatively. As a solution to deal with such abdominal incision, in recent years, a novel procedure has been carried out, named natural orifice specimen extraction (NOSE) surgery, and been widely used in many countries, due to its benefit of no abdominal wound, fast recovery post-operatively, decreased morbidity of incision complications and reduced post-operative pain complaint.[3–5] Considering majority of clinical studies which argue that NOSE has certain advantages, a point view seems to be prevalent that NOSE could be a safe surgical method, comparing with laparoscopic colectomy.

Although it is a prevailing option that NOSE has many benefits, limitations of such surgical procedure still should not be disregarded. Among common post-operative complications, such as anastomosis leakage, anastomosis bleeding and pelvic abscess, we here reported a case with a unique and rare complication of an overwhelming infection, different from some common inflammation post-operatively, hoping that this case could remind surgeons NOSE is a procedure with strict indications, which is not suitable for every colonic carcinoma case, also can lead to some certain fatal complication, which surgeons have to pay attention to.

A written informed consent statement was obtained from the patient, following approval from the Institutional Ethics Committee of the Second Hospital of Jilin University.

Chief complaints

A 62 year old female patient presented with a complaint of an intermittent right abdominal pain for 2 months.

History of present illness

This female patient has suffered an intermittent dull pain in the right upper and lower abdominal quadrant for about 2 months. Her complaint was without radiating abdominal pain, without abdominal distension, or without nausea and vomiting. Dark yellow to black stool was discovered for recent 7 days, with reduced frequency of bowel movement, which is about 1 bowel movement for 3–4 days. However, other characteristics of stool was as usual, without pus. She did not receive any hospital service during this period. She only took some laxative for bowel movement. The abdominal pain was improved temperately after medicine taken.

History of past illness

This patient had a history of hypertension for 10 years, with a highest record of 160/90 mmHg. Her blood tension was controlled at around 130/85 mmHg by taking medicine regularly. She denied a history of coronary heart disease or other concomitant diseases. She also denied any history of smoking and drinking. She did not receive any surgery before. Her father died from heart attack, and her mother died from pulmonary infection.

Physical examination

A physical examination showed us that her overall condition was relatively normal: body mass index (BMI), 23.4374 kg/m²; blood pressure, 122/83 mmHg; heart rate, 86 beats per minute; respiratory rate, 16 breaths per minute; oxygen saturation, 100% on room air; and body temperature, 36.5°C. Abdominal examination presented a right upper abdominal quadrant tenderness pain, without rebound tenderness or muscular tension. Rectal examination (knee-chest position) had no significant findings.

Laboratory examinations

Routine laboratory examinations showed that this patient had relatively normal complete blood counts, with white blood cell count (WBC), 5.0⋅10⁹ cells/L (normal range is 3.5-9.5⋅10⁹ cells/L); percent of neutrophil granulocyte (NG), 67.90% (normal range is 40.00–75.00%); red blood cell count (RBC), 4.16⋅10¹² cells/L (normal range is 4.30-5.80⋅10¹² cells/L); hematocrit (HCT), 33.70% (normal range is 40.00%-50.00%); platelet count (PLT), 278⋅10⁹ cells/L (normal range is 125-350⋅10⁹ cells/L). Tumor markers examinations also presented a normal result, with carcinoembryonic antigen (CEA),1.55 ng/ml (normal range is 0–5 ng/ml); and carbohydrate antigen 199 (CA199), 7.23 U/ml (normal range is 0–37 U/ml). Blood examinations for cardiac function were performed, as b-type natriuretic peptide (BNP), 145 pg/ml (normal range is 0-100 pg/ml); troponin, 0.001 ng/ml (normal range is 0-0.03 ng/ml).

Imaging examinations

A colonoscopy revealed the existence of a neoplasm at 70 cm from anal edge, which had an uneven surface, surrounded by congestive and edematous mucosa. This neoplasm invaded almost 3/4 circumstance of lumen, leading to a bowel obstruction. As a result, the rest of colon could not be scoped. 4 tissue specimens were then obtained from this neoplasm for further pathological biopsy. The biopsy result confirmed a diagnosis of colon carcinoma. A followed computed tomography (CT) scan was performed, with a finding of a tumor-like manifestation at middle site of ascending colon. No swollen lymph nodes was detected surrounding this tumor or retroperitoneum. (Fig. 1)

Final diagnosis

Based on the coloscopy finding, the result of pathological biopsy, and the CT image, a diagnosis of ascending colonic carcinoma was made. (cT₃N₀M₀)

Brief surgical procedure

Once a clinical diagnosis was made, following a routine short-term colon and vaginal antibiotic preparation, a surgical treatment of laparoscopic right hemi-colonic radical resection with transvaginal natural orifice specimen extraction procedure was finally performed on this patient at 12th day after admission. A standard procedure of laparoscopic right hemi-colonic radical resection was performed firstly, of which dissection of mesenteric vessels and lymphadenectomy were guided by the landmark of the superior mesenteric vein (SMV). A specimen of a 20 cm long ileum from ileocecal valve, ascending colon and partial transcending colon was acquired when such radical resection was finished. Next step was packaging this specimen into a prepared plastic retrieval bag. Then an around 5 cm incision at posterior wall of vagina was performed, in order to fulfill the requirement of specimen extraction from vagina as a natural orifice. The operation time was 125 min, with only 50 ml blood loss occurring.

Histopathological findings

The middle-low differentiated adenocarcinoma, with component part of mucinous adenocarcinoma. The carcinoma cell infiltrated the serous layer of intestinal wall, and the vein tube was detected carcinoma cell invading. No metastasis evidence was found at ileum, greater omentum or appendix. No metastasis of lymph nodes were found around colon (0/20) or around ileum (0/5). Finally, pTNM staging was T3N0Mx.(Fig. 1) An immunohistochemical examination followed. The outcomes were as follows: P53 (30% positive), Ki67 (80% positive), BRAFV600E(1positive), MLH1 (negative), MSH2 (positive), MSH6 (positive), PMS2 (positive), CDX2 (positive), EGFR(positive).(Fig. 2)

Post-operative treatment

At the 1st day post-surgery, blood pressure, 84/45 mmHg; heart rate, 110 beats per minute; respiratory rate, 24 breaths per minute; oxygen saturation, 95% on oxygen uptake through mask; and body temperature, 38.9°C. The patient complaint a sleepy, weak, hard breathing and fever condition. Her blood examination showed that WBC was 4.3⋅10⁹/L, percent of NG was 93.20%, percent of lymphocyte was 3.30%, RBC was 3.94⋅10¹²/L, Hb was 105g/L, HCT was 32.80%, PLT was 130⋅10⁹/L, BNP was 4546 pg/ml and troponin was 11.272 ng/ml. At that moment, a diagnosis of septic shock and acute cardiac functional failure has been made out. An antibiotic medicine upgrading was immediately carried out. Meantime, this patient was transferred to our intensive care unit (ICU) for further treatment. At the 2nd day post-surgery, she experienced a sudden cardiac arrest with loss of consciousness. An cardiac emergency therapy was executed, including an electric defibrillation. The state of cardiac arrest came over shortly, with a manifestation of blood pressure 102/80 mmHg, heart rate 102 beats per minute, respiratory rate 18 breaths per minute, oxygen saturation 99% on oxygen uptake through mask. At that day, the values for assessing infection severity included procalcitonin 11.643 ng/ml (normal range is 0-0.5 ng/ml), interleukin-6 (IL-6) 1312.35 pg/ml (normal range is 0-6.4 pg/ml). An antibiotic therapy continued according blood examinations. Other supportive treatments were also given depending on the patients’ conditions and examinations. The values about infection, immune system and cardiac function were all listed in Fig. 3–6.

This patient was almost recovered at 12th day post-surgery, with a normal range of blood pressure 124/80 mmHg, heart rate 78 beats per minute, respiratory rate 16 breaths per minute, oxygen saturation 100% on room air. However, an intermittent precordial pain still existed. After a complete physical and laboratory examination by a doctor from the department of cardiovascular internal medicine, this patient was transferred from our department to cardiovascular internal medicine department for further cardiac treatment. After anther 18 days treatment, she discharged from our hospital.

Outcome and follow-up

After her discharged from our hospital, a six month follow-up was performed by telephone. A blood examination was advised to perform to monitor levels of CEA and CA-199 per 3 months until 2 years post-surgery. Neither a CT scan or a Magnetic Resonance Imaging (MRI) was also suggested to performed per 6 months post-surgery to discovery any evidence of potential recurrence. At the same time, the patient was strongly suggested to undergo 6–8 cycles of CapeOx chemotherapy. Until now, this patient has finished 6 cycles, without experiencing any serious adverse effects, such as neurotoxicity and bone marrow suppression, or any findings of recurrence.

Comparing with conventional laparoscopic abdominal surgeries, one of most obvious advantage of NOSE procedure is absence of an abdominal auxiliary incision, along with minimizing access trauma. Considering incision pain and some incision healing associated issues, NOSE procedure theoretically could reduce use of anesthetic drug for releasing incisional pain and morbidity of incision complications, such as incision hernia and wound dehiscence. [6] For abdominal specimen extraction, transvaginal approach, as one of two mainstream approaches, of which another is transanal approach, has been regarded as a common, uncomplicated and widely used method, due to the reason that vaginal wall is elastic, a larger specimen can be acquired through it.[7–9] Besides this present case colon specimen from right hemicolectomy, gastric specimen from subtotal gastrectomy, liver specimen from liver resection and partial pancreas specimen from distal pancreatectomy are reported to be obtained from vaginal wall incision during NOSE.[10–13] Luyao Zhang et al. have successfully performed laparoscopic pancreaticoduodenectomy through transvaginal NOSE method.[14]

Although advantages of laparoscopic transvaginal NOSE are well recognize, some risks and complications have been observed and drawn attention by surgeons recently. Even though both the amount and length of abdominal incision are reduced maximally, wound infections are still reported occasionally.[8 15] Anastomotic leakage, as one of post-operative complications of conventional laparoscopic surgery, is also observed post laparoscopic transvaginal NOSE.[16 17] Other complications, such as bleeding, internal hernia and abdominal abscess, still exist. Moreover some complications are unique for such NOSE procedure. Abdominal contamination, one of such complications, has already been observed.[4 18]

This present case has experienced an overwhelming infection after laparoscopic transvaginal NOSE procedure for right hemi-colonic radical resection. According to her post-operational clinical examinations files and physical examination findings, abdominal contamination is highly suspected. The reasons for such a rapid infection aggravation, even a septic shock appearance, acute cardiac functional failure and a sudden cardiac arrest are still uncertain, however, immune system dysfunction is supposed to be responsible. As shown in Fig. 5, the count of T and B lymphocytes and the count of Natural Killer cells (NK cells) have fallen down to the lowest level at the 3rd day post-operation, which led to cell and humoral immune response largely weaken. There could be an interactive relationship and reciprocal causation between a septic shock and immune dysfunction. Furthermore, the amount of immunocytes has not risen up to a normal level when she was transferred to cardiovascular internal medicine department with a normal level of WBC and NG, which might be a reminder that some immune-related malfunction can exist even pre-operationally.

In order to reduce transvaginal NOSE related complications, procedures pre-operation and intra-operation in our department follow these protocols: a) bowel preparations pre-operation are mandatory and indispensable, including intestinal antibiotics application and cathartics for thorough evacuation of lumen; b) preventive disinfected vagina preparation with iodine solution is performed; c) assessment about immune system function, if necessary, can be done; d) carefully and skillfully cope with suturing incision on posterior vaginal wall; e) properly handle the process of packaging surgical specimen by using retrieval bag. The last protocol should be top crucial among all these protocols depending on our experience. Preventing surgical specimen leakage, especially lumen contents, is not only a consideration on avoiding malignant tumor cells spreading, but also escaping from bacterium invading into peritoneal cavity.

For a novel surgical procedure, it is always top concerned and frequently discussed that short-term and long-term complications, overall survival (OS), disease-free survival (DFS) and intro-surgery safety, including abdominal contamination, distal resection margin results and number of retrieved lymph nodes. Most studies argued that this procedure of NOSE could receive an equal or even a lower incidence of abdominal contamination and intro- and post-surgery infection, compared with laparoscopic surgery.[4 18–20] In terms of short-term complication, abdominal contamination and consequent intra-abdominal infection are crucial issues. To evaluate and prevent infection, Linke GR et al performed bacterium growth routine culture examination through gathering swaps from vaginal posterior fornix and peritoneal cavity at different intervals post-surgically.[21] Some interventions, such as preoperative administration of prophylactic antibiotics, preoperative intestinal lumen preparation, intraoperative peritoneal irrigation, and intraoperative transanal lavage with iodophor water, are recommended by different clinical centers, coming out with promising outcomes.[19 20] However, due to a consideration of possibility of carcinoma cells spreading, our group does not apply intraoperative transanal lavage.

We have performed an analysis on intra-abdominal complications associated with colorectal NOSE surgery for recent years. (Table 1) As shown in Table 1, intra-abdominal infection is one of short-term complications with a low incidence. There has been no reports about an over-whelming infection post-surgery yet. However, infection after laparoscopic transvaginal NOSE procedure is still a short-term complication which should be paid attention to by each surgeon.

Totally speaking, laparoscopic NOSE procedure is one kind of minimal invasive procedures, characterized as a safe, cosmetics surgical method with less short- or long-term complications and fast recovery when compared with conventional laparoscopy. However, some complications, such as anastomotic leakage and wound infection, still happen occasionally. This case report presented an extreme rare case experiencing an overwhelming intra-abdominal infection post-surgically, which even caused a sudden cardiac arrest. It should be an alert for each surgeon towards NOSE preparations, surgical procedures and complications.
