[Minimally invasive esophagectomy: prospective evaluation of laparoscopic gastric mobilization].

OBJECTIVE: Esophagectomy carries high morbidity, mainly due to respiratory complications. In digestive surgery, postoperative outcome is generally improved by minimally invasive surgery. A prospective study was conducted to evaluate feasibility and postoperative outcome of minimally invasive esophagectomy (MIE). METHODS: From July 2001 to June 2004, 20 patients underwent esophagectomy with laparoscopic gastric mobilization (LGM) for squamous cell carcinoma (N=11), adenocarcinoma (N=7), Barrett's esophagus with high-grade dysplasia (N=1), and long peptic stricture (N=1). Tumours (N=19) were located on the cardia (N=5), on the lower third of the oesophagus (N=10), on the median third (N=3), and on the upper third (N=1). Following LGM, transthoracic (N=19) or transhiatal (N=1) oesophagectomy was performed. RESULTS: Complete LGM was achieved in all cases. Mean operative time for LGM was 197+/-48 minutes. In the 19 patients operated for tumours, 18 underwent R0 resection. Eleven patients (55%) developed postoperative complications, mainly (30%) respiratory. Intrathoracic anastomotic leakage occurred in 2 patients, with favourable outcome. Pylorospasm (N=1) was the only intraabdominal complication. One patient died (5%). CONCLUSION: Esophagectomy with LGM is feasible with few specific complications. However, no decrease in morbidity could be observed with this technique. Further studies are required to evaluate if thoracoscopy could improve the postoperative course after LGM and to validate oncologic safety of MIE.

[Extensive digestive caustic burns: what are the limits for resection? A series of 12 patients].

AIM OF THE STUDY: To report the results of oesogastric resections extended to surrounding organs following caustic ingestion, and to precise indications for resection and results of reconstruction. PATIENTS AND METHODS: From 1988 to 2001, 12 patients underwent oesophago-gastrectomy, extended to duodenum and pancreatic head (n = 6), jejunum (n = 4), colon (n = 2), spleen (n = 2) or pancreatic body (n = 1). Early morbidity and mortality, specificities of reconstruction, and quality of oral feeding were assessed retrospectively. RESULTS: Mean intensive care unit stay was 50 days (range: 16-152 days). All patients developed complications. Six patients were reoperated for secondary extension of caustic burns, mainly to colon (n = 4), small bowel (n = 2) and pancreas (n = 2). Three patients died on postoperative days 17, 20, and 130. Secondarily, eight patients (75%) underwent a substernal right ileocoloplasty. Six patients (50%) survived initial resection, and esophageal reconstruction. After a mean follow-up of 35 months (range: 7-87 months), four patients (33%) eat normally. CONCLUSIONS: After caustic burn, oesogastric resections extended to surrounding organs are associated with high morbidity and mortality. However, return of normal oral feeding can be expected in 33% of cases. Secondary extension of caustic burns to adjacent organs is a common eventuality, and may lead to prompt reintervention. Massive injury to small bowel or colon may compromise digestive function or secondary esophageal reconstruction, and thus may be the reasonable limit for resection.

[Diagnostic and therapeutic management of digestive caustic burns].

Caustic burns of the upper gastrointestinal tract are a common emergency. Outcome is generally favorable. Endoscopic fiberoptic examination is the most accurate exam for evaluation of the extent of corrosive injuries. In case of severe caustic burns, surgical intervention allows removal of necrotic tissues, and prevent the extent of burns to the adjacent organs. Blunt esophageal stripping, combined with total gastrectomy is then the intervention of choice. Superficial burns usually recover without sequela, or with esophageal or gastric stenosis. Secondary coloplasty is advocated for treatment of failure of endoscopic dilatations, and for digestive reconstruction after initial esophagogastrectomy.

Serial computed tomography is rarely necessary in patients with acute pancreatitis: a prospective study in 102 patients.

BACKGROUND: CT has proved to be helpful in patients with acute pancreatitis for differentiating between mild and severe forms. Followup of acute pancreatitis with CT has been advocated but rarely studied. The aim of this study was to determine if late CT performed at day 7 might be helpful in establishing the prognosis or the type of complications, and to select a subgroup of patients in whom CT could be beneficial. STUDY DESIGN: Contrast-enhanced CT was performed at the admission day and 7 days after admission in 102 patients admitted for acute pancreatitis. The extent of pancreatic inflammation was classified according to Balthazar grade, and intrapancreatic necrosis on these examinations was prospectively assessed and compared with clinical and biologic data and with patient outcomes. RESULTS: Among 102 patients, complications developed in 24 (23%). Complications developed in only 8% of patients with Ranson score <2, making routine early CT unnecessary. For the patients with Ranson score <2 and Balthazar grades A and B at day 1 CT, late CT seemed to be useless. Complication was suspected by clinical and biologic tests before day 7 in 22 of 24 complicated patients (92%), suggesting that CT could be proposed only in cases of clinical or biologic deterioration. Late CT was correlated with a complicated course in patients with Balthazar grades D and E or intrapancreatic necrosis >50%. Late CT was predictive of complications in cases of intrapancreatic necrosis enlarging since the first examination. CONCLUSIONS: Our study showed that in acute pancreatitis: 1) there is little justification for systematic early CT, especially in patients with Ranson score <2, and 2) late CT does not need to be performed routinely, but only in cases of clinical or biologic worsening.

Extensive abdominal surgery after caustic ingestion.

OBJECTIVE: To report the authors' experience in extensive abdominal surgery after caustic ingestion, and to clarify its indications. SUMMARY BACKGROUND DATA: After caustic ingestion, extension of corrosive injuries beyond the esophagus and stomach to the duodenum, jejunum, or adjacent abdominal organs is an uncommon but severe complication. The limit to which resection of the damaged organs can be reasonably performed is not clearly defined. METHODS: From 1988 to 1997, nine patients underwent esophagogastrectomy extended to the colon (n = 2), the small bowel (n = 2), the duodenopancreas (n = 4), the tail of the pancreas (n = 1), or the spleen (n = 1). Outcome was evaluated in terms of complications, death, and function after esophageal reconstruction. RESULTS: Five patients required reintervention in the postoperative period for extension of the caustic lesions. There were two postoperative deaths. Seven patients had secondary esophageal reconstruction 4 to 8 months (median 6 months) after initial resection. Three additional patients died 8, 24, and 32 months after the initial resection. Three survivors eat normally, and one has unexplained dysphagia. CONCLUSIONS: An aggressive surgical approach allows successful initial treatment of extended caustic injuries. Early surgical treatment is essential to improve the prognosis in these patients.

[Vascular control during left splenopancreatectomy in cancer].

Distal pancreatectomy remains the gold standard for resection of left-sided pancreatic carcinoma. For oncologic and surgical reasons, the control of splenic vessels is an important phase of this operation. Based on anatomical considerations, the two resection techniques are presented in this paper: by first dividing the pancreatic neck or by first removing the spleen.
